Fire Proof, Corrosion Resistant Cable Clamps - Ellis Patents Phoenix Cleats

Ellis Patents Phoenix Cable Cleats

The Ellis Patents Phoenix range of fire proof cable clamps are specifically designed for the installation and support of Fire Protection (FP) rated cables.

Manufactured by Ellis Patents from Type 316L stainless steel with single bolt fixing, Phoenix Cable Cleats are available in 11 sizes to suit single cables from 10mm to 65mm in outside diameter.

To prove the fire resistance of Ellis Patents Phoenix cleats and clamps they were used to secure a fire rated cable during a series of tests in accordance with BS 5839-1:2002, Section 26.2d.

Phoenix cleats successfully supported the cable during the test and the performance was as expected given the physical characteristics of 316L stainless steel at elevated temperatures.

  • Max S/C Test Level 60kA
  • Cable Cleat Spacing 600mm

Why Engineering Consultants Must Specify Ellis Patents Phoenix Fire Resistant Cable Cleats for Building Services and Industrial Projects

“To date there has been no agreed test for a cable cleat to be put through in order to rate its fire performance,” said Ellis Patents managing director, Richard Shaw. “Instead cast iron cleats, which have a melting point high enough to provide the necessary safety reassurances, have generally been used.

“The drawback to this approach is that cast iron is costly, which makes such cleats restrictively expensive. And with a significant growth in the number of FP installations the clamour for a more cost effective solution has been growing.”

The cable cleat fire resistance tests included exposure to fire, impact and water spray - all of which combined to ensure that the Ellis Patents Phoenix cable cleat range offers fire protection to the same level as the cables it will be installed to protect.

“As with anyone bringing a new product to market Ellis Patents are delighted to be first off the mark, but I do feel that the fact we were faced with developing a new product without the guidance of an industry agreed testing procedure once again highlights the severe lack of understanding when it comes to the role cable cleats play in any cable installation,” added Richard Shaw.

“In a standard short circuit situation, underspecified cable cleats will simply add to the shrapnel, therefore putting lives and expensive cable installations at unnecessary risk. Similarly, put underspecified cable cleats on a fire rated cable installation and any benefit such cabling may bring to a building is instantly lost."
